Pengaruh Konsentrasi Chemical Biological Demand (Cod) Dan Ragi Terhadap Kinerja Dual Chamber Microbial Fuel Cells (Dc-mfcs)

Microbial Fuel Cells (MFCs) is a kind of eco-friendly technology and become the future energy resource which is use organic fuel cells that utilize microorganism to convert directly biochemical compounds to energy, the result that suitable for extreme condition, such as waste treatment. In order to improve MFCs performance which is to obtain maximum COD removal and electricity generation, COD concentrations and yeast agent were varied. The system used dual chamber reactor and operated in two phases. Acclimatization phase on 13 days, and running phase on 35 days. COD concentrations varied on 400 mg/l, 800 mg/l, 1,200 mg/l, and yeast agent on 1.5 g/l; 3 g/l; 4.5 g/l. The result were COD removal efficiency obtained at 800 mg/l, 95.1 %; 400 mg/l, 94.8%; 1,200 mg/l, 92.7 %. And the optimum is 1,200 mg/l COD concentrations with 3 gr/l yeast agent, 506,63 mW/m2 dan COD removal obtained 92%
